Update OpenShift CLI Binaries on Harness Delegates

When you install and run a new Harness Delegate, Harness defaults to OpenShift CLI version v4.2.16.

In some cases, you might want to use one a different binary. For example, you might want to use oc command options only available in a more recent version.

Updating the OpenShift CLI is as simple as adding the binary to the Delegate host(s), changing the OC_VERSION environment variable, and then starting or restarting the Delegate.

Before You Begin​

Step 1: Download the OpenShift Binary​

To install the OpenShift CLI (oc) binary on Linux or Windows, do the following.

Navigate to the OpenShift Container Platform downloads page on the Red Hat Customer Portal.

Select the appropriate version in the Version drop-down menu.

Click Download Now next to the OpenShift v4.x Linux Client or OpenShift v4.x Windows Client and save the file.

Unpack the archive (tar xvzf <file>).

Place the oc binary in a directory that is on your PATH (for example, client-tools/oc/v4.x.x).

Step 2: Update OC_VERSION​

The host must have an exact match between the OC_VERSION value (typically, in the .bashrc file) and the path of the library in client-tools/oc/$OC_VERSION.

Update the OC_VERSION environment variable on the host system with the new version number.

If the version number is not added, Harness defaults to v4.2.16.

Step 3: Restart the Delegate​

Each type of Delegate uses a configuration file that you must use to restart your Delegate.

Here are the different types of Delegates and the configuration restart commands:

  • Kubernetes: kubectl apply -f harness-delegate.yaml
  • Shell Script: restart the Delegate with ./stop and then ./start.
  • Helm: helm install --name helm-delegate-doc harness/harness-delegate -f harness-delegate-values.yaml
  • Docker: ./launch-harness-delegate.sh
